A wave energy power generation device based on self-adaptive pressure regulation of a gradually expanding cone pipe

Abstract

This invention discloses a wave energy generation device based on adaptive voltage regulation using a gradually expanding conical tube, comprising a base support assembly, which includes an outer floating frame and a sealed shell disposed in the middle of the outer floating frame. Multiple connecting arms extend circumferentially inward from the upper end of the sealed shell. A fluid power generation assembly includes an energy collecting tube fixedly disposed inside the sealed shell and having a vertical flow channel, and a pressure-bearing piston slidably disposed inside the energy collecting tube. The inner cavity of the energy collecting tube is a gradually expanding conical structure with its inner diameter gradually increasing from bottom to top along the axial direction. The inner diameter of the pressure-bearing piston is constant, and its outer peripheral wall defines an annular leakage channel with the inner peripheral wall of the energy collecting tube. This invention ensures high power generation efficiency under low-pressure conditions with high sealing performance and safety under large waves with large clearance at high pressure, thus increasing the average annual power generation hours.
